Nicolas, this can be done by using the commands from here: http://mailman.alsa-project.org/pipermail/alsa-devel/2015-June/094080.html
In particular: amixer -c0 sset 'codec_out0 mix 0 pcm0_in' on amixer -c0 sset 'media0_out mix 0 media1_in' on
Thanks for the explanations, that saved me a lot of time.
It changed the result a bit. Now, aplay fails, but it takes one or two seconds before starting ("Playing raw data...") and again one or two seconds before failing ("Unable to install hw params:..."). In the meantime, the kernel printed this:

I have attached the full output of amixer in case it is useful. I am shooting in the dark here. Is there a documentation to understand what all these settings do?
